Hi Corby, I don't doubt it for an instant. Oil pumps just don't hack it for UHV.
If you are going to use oil pumps for almost anything serious you must use an LN2 trap. In a He Leak Detector, for example, an oil system is often used. BTW, Varian specifically say not to use Silicone oils as they permanently destroy the mass specs. Do you have an RGA on your MASER?
